# H-type double gallbladder malformation: a case report

## TL;DR

A rare case of an H-type double gallbladder is reported, highlighting the importance of preoperative diagnosis to avoid surgical complications.

## Contribution

The paper presents a rare anatomical variant of the gallbladder with clinical implications for biliary surgery.

## Key findings

- An H-type double gallbladder was identified during laparoscopic cholecystectomy in a 21-year-old male.
- The patient had cholelithiasis and cholecystitis confirmed by pathology.
- The patient recovered well post-surgery, emphasizing the need for preoperative recognition of such anomalies.

## Abstract

Biliary tract malformations are rare congenital anomalies, occurring in approximately 1 in 4000 individuals that may predispose to cholelithiasis and increase surgical risks, emphasizing the need for precise preoperative diagnosis. We report a 21-year-old male with recurrent biliary colic found to have a rare "H-type" duplex gallbladder during laparoscopic cholecystectomy—two separate gallbladders with independent cystic ducts. Pathology confirmed cholelithiasis with cholecystitis. The patient had an uncomplicated recovery with discharge on postoperative day 1. This case underscores the importance of recognizing such anatomical variants preoperatively to minimize surgical complications in biliary procedures.
